, none have yet developeda marketable product, but it appearsthat it will only be a matter of timebefore they do. The Sandia scientists who devel-oped the goggles, C. B. McCampbell,G. H. Haertling, J. T. Cutchen andJ. O. Harris, also point out that hadsuch a lens been used on the ApolloTV camera that burned out when itwas inadvertently pointed at thesun, that camera might still beworking and capable of sendingback valuable information to earth.Equally important applicationscould be made of the material inphotographic lenses and filters. One relatively early Sandia dis-covery, the use of ultra-clean air toreduce contamination when assem-bling subminiature electronic com-ponents, was made available for in-dustrial application more than tenyears ago. Today, there are at least40 firms in the business of design-ing, manufacturing and installingthe highly effective laminar-flowclean rooms, clean benches and re-lated equipment.

Thefirst time laminar air flow wastested under surgical conditions wasin an operation on a dog in 1962. Itwasnt until 1966, however, that thenations first laminar air flow oper-ating suite was opened at Albuquer-ques Bataan Memorial Hospital.Now, hundreds of hospitals all overthe world are installing such suites. The principle of laminar air flow,like most great inventions, is sim-ple. A carefully controlled supply ofair is sent through a bank of highlyefficient filters, which remove allparticles over a millionth of an inchin diameter from the air. This sup
